Attach air tube (if not already installed)

If using a ﬂ ange and gasket, slide them onto the air

tube. Then attach the air tube to the burner chassis

using the four sheet metal screws provided. Refer

to Figure 3 for details.

Install burner nozzle (if not already in-

stalled)

Remove the plastic plug protecting the nozzle

adapter threads

Place a ¾" open-end wrench on the nozzle adapter.

Insert the nozzle into the adapter and ﬁ nger tighten.

Finish tightening with a ⅝" open-end wrench. Use

care to avoid bending the burner head support legs

or electrodes. If you remove the head to replace

the nozzle (type "L1"/"L2" or "V1" heads), carefully

reconnect the head to the nozzle adapter, making

sure that the head support makes contact with the

nozzle adapter shoulder. Refer to Figure 4 or 5.

70° or 80° nozzle

45°, 60°, or 70° nozzle

If the nozzle is already installed, remove the noz-

zle line assembly to verify that the nozzle size and

spray pattern are correct for the application (per ap-

pliance manufacturer's information). Verify that the

electrode tip settings comply with Figure 2.

If the nozzle is not installed, obtain a nozzle from

the manufacturer, having the capacity and spray

0.56

angle speciﬁ ed in the appliance manufacturer's in-

0.71

formation. For conversions or upgrades, when in-

0.85

formation is not available for the application:

Refer to Table 6 to select the mid-range nozzle

0.92

spray angle for the head type being used.

Fire the burner and make sure the combustion

1.20

is acceptable and the ﬂ ame is not impinging on

1.27

chamber surfaces.

1.41

If a shorter ﬂ ame is needed, select a wider spray

1.56

angle. If a longer ﬂ ame is needed, select a nar-

1.70

rower spray angle.

Either hollow or solid spray patterns may be used.

1.77

If combustion results are not satisfactory with the

1.91

selected spray pattern, try the other pattern.

Check/adjust electrodes

2.48

Check the electrode tip settings. Adjust if neces-

2.83

sary to comply with the dimensions shown in Fig-

ure 2. To adjust, loosen the electrode clamp screw

and slide/rotate electrodes as necessary. Securely

tighten the clamp screw when ﬁ nished.
